Part B. Carry out the experiment the way you described it in task 1, part D. Perform three trials for each drop height, and record
the data in the table. Estimate heights to the nearest centimeter. (You may choose to reduce the simulation rate and
watch the bounces in slow motion to improve your data collection.) Finally, average the bounce height measurements
to get a final reading. Round the average bounce heights to the nearest whole number.

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

Compare and contrast the bohr model and the electron cloud models of the atom.
